Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon.The forest's different levels support an unbelievable variety of wildlife. 3 What's more, more than 1,300 species of birds and over 400 species of mammals hide among the jungle's plant life. The Amazon rainforest breathes life into the planet by fixing carbon and producing over 20 per cent of all the Earth's oxygen. 4 Moreover, the Amazon rainforest is a treasure house of species that can be used for food or medicine.Yet there is one major danger to these irreplaceable plants and animals: us.Over the past 50 years, about 17 per cent of the rainforest has disappeared due to human activities such as agriculture and cattle farming. 5 We are left with a question: can we afford to damage the “lungs of the planet”？ A．Thus, it is often known as the “lungs of the planet”． B．Each level forms its own little world, home to different kinds of living things.

[语篇综合训练] Ⅰ.阅读理解 More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments.Covering an area of over 4,000 square kilometers, Qinghai Lake is also the country's biggest salt-water lake.Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point — Cormorant Island and Egg Island.The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds.The islands have become a paradise for different kinds of groups of birds and have been called “Bird Islands”． Each March and April, when ice and snow covering the Qinghai-Tibet Plateau start to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs.During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere.Visitors can hear the singing of birds from miles away.These have become a world-famous symbol of the lake. To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997.Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones. Inspection officials and management employees often patrol the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors.They are making great efforts to call on people to love and protect the birds.At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous (食肉的) animals, as well as illegal hunters from breaking up the birds' nest-building, egg-laying and breeding.As a result, more and more birds are coming to the islands for sheltering and breeding. 语篇解读：本文是一篇说明文。文章主要介绍了越来越多的鸟类来到青海湖，当地政府采取了有效的保护措施，使这个地方成为鸟类的天堂。 1．Why are more and more birds coming to the biggest salt-water lake in the great Northwest? A．It is getting warmer and warmer. B．It is being reformed. C．Environments there are getting more and more agreeable for them to live in. D．The people there are becoming richer and richer. √ 解析：推理判断题。根据第一段第一句可知，多亏了当地政府的保护，越来越多的鸟类迁徙到青海湖。由此可推知，青海湖是一个适宜鸟类生活的地方。 2．What do the birds feed on according to the passage? A．Floating fish and various grass. B．Grass moving on the water surface and different kinds of fish. C．Salt water and plenty of grains. D．Corn from the local farmers. √ 解析：细节理解题。根据第一段中的“plenty of floating grass and various schools of fish, offering rich food sources for birds”可知，鸟类是以水草和各种鱼类为食的。 3．Which of the following statements is TRUE according to the passage? A．The ice and snow covering the Qinghai-Tibet Plateau won't change into water unless more than 20 kinds of birds come to the Bird Islands. B．Flocks of birds fly up to the whole sky over islands to lay eggs. C．Visitors can listen to the singing of birds from miles away, but they couldn't see any bird. D．“The ice on the Plateau begins to change into water” means spring is coming. √ 解析：推理判断题。根据第二段中的“Each March and April, when ice and snow covering the Qinghai-Tibet Plateau start to melt”可知，每年的三四月份，冰雪开始融化，这意味着春天来了。 4．The officials go around the lake mainly to . A．let the farmers there know the animal protection law B．tell the farmers there some knowledge about animal protection C．call on people to love and protect the birds D．all of the above √ 解析：细节理解题。根据最后一段前两句可知，政府官员经常巡视湖泊是向当地人们普及动物保护法，宣传保护动物的知识，并呼吁人们爱护鸟类。 Ⅱ.完形填空 Natalie and Callie, both 13 years old, started raising monarch butterflies (黑脉金斑蝶) for fun in 2020.But after realizing monarch butterflies were an endangered species, their 5 soon turned into a serious mission.

This is a bad 3 (predict) for some 1.9 billion South Asians, 4 use water from these glaciers not only for drinking but also for agriculture，hydroelectric power (水力发电), and tourism.But the survey also looked at an immediate question: As the glaciers 5 (rapid) melt，where will all the water — more than a quadrillion gallons of it, almost the amount 6 (contain) in Lake Huron — go? The answer is that the Himalaya, for example, long defined by 7 (it) glaciers, is becoming a mountain range defined by lakes.In fact, another study found that from 1990 to 2010, more than 900 new glacier-fed lakes 8 (form) across Asia's high mountain ranges.Because of those remote locations, scientists must rely 9 satellites to count them, and new lakes appear to be growing so quickly that it's difficult for scientific teams to agree on the precise number. It's all happening much 10 (fast) than we expected it to even five or ten years ago. 语篇解读：本文是一篇说明文。文章介绍了气候变暖加速了冰川的融化，这给依靠冰山取水的地区以及喜马拉雅山脉都带来了极大的影响。 1．the　考查冠词。根据空后表示范围的“up to now”可知，此处应用最高级。形容词最高级前应使用定冠词the。 2．warning　考查非谓语动词。分析句子结构可知，空处应填非谓语动词作伴随状语；warn与主语the International Centre for Integrated Mountain Development之间构成逻辑上的主谓关系，故用其现在分词形式warning。 3．prediction　考查名词。该空前面有“a bad”修饰，应使用单数名词。 4．who　考查定语从句。空处引导非限制性定语从句，且在从句中作主语，从句修饰先行词South Asians，故用关系代词who。 5．rapidly　考查副词。空处修饰动词melt，故用副词形式rapidly。 6．contained　考查非谓语动词。分析句子结构可知，contain与the amount构成逻辑上的动宾关系，故用过去分词作定语。 7．its　考查代词。空处修饰后面的名词glaciers，故用形容词性物主代词its。 8．were formed　考查动词的时态、语态和主谓一致。句子主语是more than 900 new glacier-fed lakes，与动词form构成动宾关系；时间状语是“from 1990 to 2010”，应用一般过去时，且主语为复数，故填were formed。 9．on/upon　考查介词。此处表示科学家必须依靠人造卫星来计算它们的数量。rely on/upon意为“依靠，依赖”，为固定搭配。 10．faster　考查副词的比较级。根据空前的“much”和空后的“than”可知，此处应用所给词的比较级形式。故填faster。 $$
